IMPROVEMENT IN WITCH-KEYS..

@te tlgthtlrrtftmt tu in tutti ttttrs attut mth making ymrt nt tige smite.

Be it known that I, RICHARD H. DILLY, of Regniers Mills, county of Washington, State of Ohio, have invented Vn new and useful Improvementin Watch-Keys; and I do hereby declare that the following is a fiill, clesr, and

'exact description of the construction and operation of the same, reference being had to the annexed drawings, making a. part of this specification, in which-1 Figure 1 is eview in perspectivgclosed.

Figure `2 is It view in perspective, open. `Figurev 3 isaflongitudinail section closed, showing the arrangement of ythe springs and their relation to the opening and closingpof the door. i

Figure 4, `end view of key, showing ring by which the key may be attached to guardor vest-chain. Figure'5, side elevation, closed.l Figure 6, longitudinal section, open. y Figure 7', `end view of key, showing end of pipe and catch byv vwhich the door connects 'with the spring en being. closed. l

Figure 8, side elevation, open, showing the position of the door when rendy'for use. Letter A, the door into which the pipe B is screwed, :ind to which the catch C is atteched. D, spring by Awhich the doorie kept closed. The catch C connects with the' spring D when the door is closed. E, spring by which the door is thrown open. F, ring or swivel. G', wire passing through `theend of key near the ring, one

end being screwed into the spring D. By pressing onthe end of the wire G, the spring D is pressed buch fromV the catch C; the door is immediately thrown open by the force of the spring E acting on the pipe B.

I construct my key of gold, silver, copper, brass, or zinc, or any other suitable metal; its size when eemplete 'being Seven-eighths of an inch in length, ive-eighths of'A :1n inch in width, and one-fourth of an inch in thickness. .The broad sides are made to project over one end, so that the door A- rnay pass between them on being opened. This gives strength to the door while winding the watch. The door A is made to {it between the sides, and is held to its place by means of a, rivet pnssing through one end of the door and intoench side` of the key, exactly opposite the corners, asreprcsented in fgsld, 8, :rnd 6. The pip/e B is screwed into the door A, While the door is open, and on shutting the door, the pipe B 'is thrown on the inside ofthe key. 'Ihel door, into which the pipe is screwed, is double the vthickness oi' the sides, the object being to give strength and durnbilitylto the door A. A smell `enteh ori'nsterring, C, is made nt\one cnil of the door on the inside, when the door is closed. The springs D-end E are mndeof brass, and are`hchl to their pinces two smell rivets;

as represented in iig. (i. When the door A is closed, the pipe B presses on the spring E. The spring Dv clnsps` the catch C, and the door is held to its platee. The door is opened by means ot' e small wire, G, passing through one end of the key 'near the ring F, one endof which is screwed into the spring D. By pressing on the end of the wire G, 'thef spring D is pressed beck from the catch C, and the door is thrown open by the force of .the springE operating on the end of the pipe B. Y

What I claim as r'ny invention, and 'desire to'secure by Letters Patent, is- I y The improved watch-key, consisting of the hollow ense, provided with the hinged door A, and springs E and D, when constructed as and for the purpose described. I
